    Today and past few days have been OK to great in Sligo. Granted there's been rainfall every day but now it's tough to get 24 dry hours in the West. I'd say the whole Winter we might have had 10 dry days and that might be since November. I hope its El Nino driven or I'm emigrating. Ya can't live in this when it's flooded constantly and dark too. That's why today is so nice. Blue skies and warm sun between the inevitable rain bands.

    Anyways 100mm forecast between now and February 29th so time to batten down the hatches and hide. You will see snow falling at the end of the week landing in flooded puddles. That's what Polar Maritime brings to these shores.

    I am liking the look of the charts towards the end of the first week and into the second week of March. If these verify I am presuming it will be frosty by night and nice sunshine by day? We can't get snow then it is the type of weather I really like this time of year and of course it will help massively with drying out the place.

    After the very mild February it wouldn't surprise me if this is the direction of travel during March

    meteorological winter ends so it’s bye bye Azores (see you next December) and northern blocking arrives right on cue ..

    even at +240 I think it’s odds on that it will end up like this,



  • Registered Users, Registered Users 2 Posts: 1,541 ✭✭✭esposito


    I agree. It’s probably odds on we’ll get some sort of an easterly in March. If we could even get a repeat of the “son of the beast” around St Patrick’s Day 2018 I’d take it. As long it’s snow falling and not cold rain.

    I’d normally say no too however I have yet to see a single snow flake fall this winter so I’d take a bit of snow in March.

    Snow in April? A definite no no though.



  • Registered Users, Registered Users 2 Posts: 1,710 ✭✭✭Eibhir


    It's the month we're most likely to get snow in, these past few decades. And prior to that, March snow is as common as hitting 23c in September.



  • Registered Users, Registered Users 2 Posts: 17,606 ✭✭✭✭nacho libre


    Oh it's true, it's damn true , Eibhir. We waited all winter for a proper blocking high and sure enough we will likely get one in March .



  • Registered Users, Registered Users 2 Posts: 1,710 ✭✭✭Eibhir


    I'd put money on a sleet, snow mix over the Easter weekend, the last weekend of March. Something like 2008.

    The old snow being more likely at Easter than Christmas fact too. As you say the son of the Beast/mini Beast around St. Patrick's Day 2018 was a good cold blast. What comes in late March and early April is usually snow at night only, and early in the morning. You're post equinox so quick thaws.

    You need something amazing like early April 1917 with -8c recorded. The GFA 1998 weekend brought -5c at night and memorable for being a bit colder than usual April cold.

    don’t forget the very cold March 2013 and followed by some very severe frosts in early April too.



  • Registered Users, Registered Users 2 Posts: 1,710 ✭✭✭Eibhir


    Yes. The first week of that March was calm, mild, Spring like. All change 10th March on. On the 11th, a Monday, -16c uppers were over the east of the country! Heavy snowfall in Ulster around 23rd March.

    Sryan will know but I think ice days in March in the past 100 years are extremely rare. Don't think we had one officially in 2013 or 2018.

    Two ice days at the start of March 2018, and of all places to record them, Cork!

    And another on the 18th of March (a notable late in the year contender):

    Very good. Thanks. Yes like January 1987 Cork seems to have been at the centre of coldest uppers.

    In 2013 we had ice days at home but 336m asl.

    Yeah March 2018 is the only time March has recorded ice day conditions in digitised records in Ireland back to 1942. There is no other examples at Irish stations in that time and probably even going further back. The combination of cloud cover, an extremely cold airmass (among the coldest ever recorded over Ireland) and such a strong easterly flow with lying snow is what allowed these unprecedented ice day conditions for the time of year.

    Limerick also had an ice day on 18th March 2018 (just barely with -0.1C). Crazy late.

    11th March 2013 had a very cold airmass but the easterly flow wasn't as strong and it was bright at times so the very cold 850s weren't as realised on the surface. Still though, Mount Russell in Limerick had a max of just 0.8C that day which is exceptional for the time of year.

    After a few less cold days looks like could be returning to more of what we got this week gone by with wintry showers coming in off the Atlantic and LP's about feeding in rain bands, no big winds showing up at present but could be breezy to windy at times along the coasts. Models currently showing LP running into cold air producing wintry falls including snow towards the end of the week coming. On the cold side start to Spring it would seem at present.

    Winter is over and good riddance.

    The Spring 120+ hour thread is now open for business.
